ABSTRACT

There is described a conditioning composition for conditioning, lightening and highlighting hair which comprises:  
     (i) a peroxygen compound; and  
     (ii) a conditioning agent,  
     said composition having a pH of 5 or less.  
     There is also described a method for conditioning lightening and highlighting hair which comprises treating said hair with a composition of the invention.

FIELD OF THE INVENTION

[0001] The present invention is directed to a conditioning compositionwhich is also for lightening and/or highlighting hair.

BACKGROUND OF THE INVENTION AND PRIOR ART

[0002] It is known within the art to lighten and highlight hair with aperoxygen compound such as hydrogen peroxide. An object of the presentinvention, is to provide conditioners which contain stable peroxygencompounds and thus can be used as hair lighteners and highlighters aswell as conditioners.

[0003] Current products on the market for lightening hair come in twoforms. The first is a spray leave-on peroxide solution. This product isused occasionally when the hair will be exposed to sunlight afterapplication. Examples of such products include Super Sun-In®, Super WithLemon Sun-In®, and Gradual Sun-In For Men®. Super Sun-In® has about 1.9%hydrogen peroxide at a pH of about 4.0. Super With Lemon Sun-In® hasabout 3.7% hydrogen peroxide at a pH of about 4.0. Gradual Sun-In ForMen® has about 3.7% hydrogen peroxide at a pH of about 3.

[0004] The second product for lightening hair is a system which has twocomponents: a bleaching component such as hydrogen peroxide and anothercomponent which is a bleach oil. This system requires two containersand/or two bottles, one for each of the components. These products willlighten and highlight the hair, however, often the result is damage thatleaves hair in a less than healthy state.

[0005] It is known to prepare an unstable composition by combining ableach with a shampoo or conditioner and immediately thereafter applyingthe resulting composition to the hair. This is usually done in a hairsalon and will result in the immediate lightening of the hair. Bycontrast, stable conditioner compositions which gradually lighten andhighlight the hair and which can easily be used at home are provided bythe present invention.

SUMMARY OF THE INVENTION

[0013] The invention relates to a conditioning composition forlightening and highlighting hair which comprises:

[0014] (i) a peroxygen compound; and

[0015] (ii) a conditioner vehicle which is stable in acid,

[0016] said composition having a pH less than 5.

[0017] The invention is also directed to a method for lightening andhighlighting hair which comprises administering to the hair a lighteningand highlighting effective amount of a composition comprising:

[0018] (i) a peroxygen compound

[0019] (ii) and a conditioner vehicle which is stable in acid

[0020] at a pH of less than 5, preferably about 2-4.5 and then rinsingsaid composition from the hair.

[0021] The peroxygen compound makes the conditioner composition alightening and hair highlighting composition. Peroxygen compounds arenot stable in conditioners at pH's of 5 and above. The composition ismade acidic by addition of a acid, such as a mineral acid, likephosphoric acid or sulfuric acid. However, peroxygen compounds can gointo conditioners provided that the pH is low enough.

[0022] Prior to the present invention, when peroxygen compounds wereused to lighten hair, they were often used in bleach oils, or haircoloring compositions.

DETAILED DESCRIPTION OF THE INVENTION

[0023] There are two methods to lighten and highlight hair. The firstmethod is to deposit onto the hair, molecules which color the hair. Thesecond method is to bleach the natural pigment found in the hair. Thepresent invention relates to the latter method.

[0024] Hair contains a number of different pigments, principally brownand red. When hair is bleached by chemicals or the sun, the brownpigments react faster, and therefore disappear faster than the redpigments. The change in the red to brown ratio changes the appearance ofthe hair giving more red shading to the natural color of the hair. Thisresults in the lightening of the hair. The red color that appears isperceived as highlighting of the hair.

[0025] Peroxygen compounds have been used to bleach human hair. Apreferred peroxygen compound is hydrogen peroxide. Hydrogen peroxide isstable, but will decompose under the appropriate conditions to formwater and an active species of oxygen. The active species of oxygen isvery reactive. It attacks and decolorizes the hair pigment.

[0026] It has surprisingly been found that a peroxygen compound,preferably hydrogen peroxide, is stable in a conditioner compositionwhen present in about a 0.01 wt. % to about 10 wt. % (preferably 2%).

[0027] Use of conditioner compositions which have pH's of 5 or belowstabilizes the peroxygen compound (which can be hydrogen peroxide) whichis included in said compositions.

[0028] In the compositions of the present invention, any acid that canresult in a pH of 5 or less may be employed. More specifically, any acidwhich has a pK such that it can be used to obtain a composition with apH of 5 or less, may be employed. Exemplary of such acids are anymineral acid such as sulfuric acid or phosphoric acid. Appropriateorganic acids such as citric acid may also be used.

[0029] As indicated above, the peroxide of the compositions of theinvention can be employed with any conditioner, as long as the pH is lowenough.

[0030] A conditioner agent stable to acid hydrolysis, such as a siliconecompound having at least one quaternary ammonium moiety along with anethoxylated monoquat is included in the conditioner.

[0031] A clear conditioning composition of the present inventioncomprises: a clear conditioning composition comprising a siliconecompound having at least one quaternary ammonium moiety, such as adiquaternary polydimethylsiloxane, and ethoxylated monoalkyl quat. Theeasy-to-apply, clear conditioning composition imparts excellent wet comband dry comb properties to the hair, and the hair demonstrates improvedphysical and cosmetic properties, such as gloss, thickness, softness,manageability, body and less coating.

[0032] Clear conditioning agents may also include an amidoamine saltcomprising an amidoamine compound having the chemical structure offormula I or II as shown below.

R₁—C(O)—NHR₂—N(R₃)R₄

[0033] I

[0034] or

R₁—C(O)—NHR₂—Y

[0035] II

[0036] or a mixture thereof, wherein R₁ is a fatty acid chain containingfrom about 11 to about 21 carbon atoms; R₂ is an alkylene groupcontaining from about 2 to about 4 carbon atoms; R₃ is hydrogen, amethyl group, an ethyl group, or a hydroxyalkylene group containing fromone to about 3 carbon atoms; R₄ is a methyl group, an ethyl group or ahydroxyalkylene group containing from one to about three carbon atoms;and Y is an organic heterocyclic nitrogen-containing moiety, and asufficient amount of a suitable acid to neutralize the amidoaminecompound.

[0037] These salts are described in U.S. Pat. No. 5,328,685 toJanchitraponvej et al, which is hereby incorporated by reference.

[0038] Conditioning compositions of the present invention also includecompositions which are not clear.

[0039] In addition to the above-described essential ingredients, othercommon cosmetic components and additives can be incorporated in theconditioning composition with the essential ingredients, as long as thebasic properties of the composition, and an ability to condition thehair, are not adversely affected. Such optional ingredients include, butare not limited to, humectants, inorganic salts, fragrances, dyes, haircolorants, hydrotropes, preservatives, water softening agents, acids,bases, buffers and the like. Optional components usually are present inweight percentages of less than about 2% each, and from about 5% toabout 10% by weight of the composition in total.

[0040] Other optional ingredients can be included in the conditioningcomposition to enhance the ability of the composition to condition thehair. For example, other quaternary ammonium compounds can be includedin the conditioning composition. A quaternary ammonium compound usefulin the composition of the present invention preferably is awater-soluble quaternary ammonium compound having one or two long chainalkyl groups containing from about 8 to about 18 carbon atoms. The longchain alkyl groups also can include, in addition to, or as a substitutefor, carbon and hydrogen atoms, ether linkages or similarwater-solubilizing linkages. The remaining two to three substitutes ofthe quaternary nitrogen of the quaternary ammonium compound can behydrogen; or benzyl; or short chain alkyl or hydroxyalkyl groups such asmethyl, ethyl, hydroxymethyl or hydroxyethyl groups; or mixturesthereof, either of the same or of different identity. However, anoil-soluble, water dispersible quaternary ammonium compound, eitheralone or in combination with a water-soluble quaternary ammoniumcompound, also can be used in the composition of the present invention.

[0041] An optional thickener also can be included in the clear or opaqueconditioning composition to improve composition esthetics and facilitateapplication of the composition to the hair. Nonionic thickeners in anamount of 0% to about 3% by weight are preferred. Exemplary thickenersare methylcellulose, hydroxybutyl methylcellulose,hydroxypropylcellulose, hydroxypropyl methylcellulose, hydroxyethylethylcellulose and hydroxyethylcellulose, di(hydrogenatedtallow)phthalic acid amide, crosslinked maleic anhydride-methyl vinylether copolymer, guar gum, xanthan gum and gum arabic.

[0042] The carrier of the conditioning composition is predominantlywater, but organic solvents also can be included in order to facilitatemanufacturing of the composition or to provide esthetic properties, suchas viscosity control. Suitable solvents include the lower alcohols likeethyl alcohol and isopropyl alcohol; glycol ethers, like2-butoxyethanol, ethylene glycol monoethyl ether, propylene glycol anddiethylene glycol monoethyl ether or monomethyl ether; and mixturesthereof. Non-aqueous solvents can be present in the conditioningcomposition of the present invention in an amount of about 1% to about50%, and in particular about 5% to about 25%, by weight of the totalweight of the carrier in the composition.

[0043] A composition of the present invention can be a composition thatis stable to phase or ingredient separation at a temperature of about25° C. for an indefinite period of time. For example, a clearconditioning composition of the present invention has demonstratedsufficient stability to phase and ingredient separation at temperaturesnormally found in commercial product storage and shipping to remainunaffected for periods of one year or more.

[0045] stearyltrimethylammonium chloride:

[0046] behenetrimethylammonium chloride;

[0047] cetrimonium bromide;

[0048] soytrimonium chloride;

[0049] tallowtrimonium chloride;

[0050] dihyrogenatedtallowdimethylammonium chloride:

[0051] behentrimethylammonium methosulfate;

[0052] Peg-2 Olealmonium chloride;

[0053] dihyrogenatedtallowdimethylammonium bromide;

[0054] dihyrogenatedtallowdimethylammonium methosulfate;

[0055] palmityltrimethylammonium chloride;

[0056] hydrogenated tallowtrimethylammoniurm chloride;

[0057] hydrogenated tallowtrimethylammonium bromide;

[0058] dicetyldimethylammonium chloride

[0062] cetrimonium tosylate:

[0063] eicosyltrimethylammonium chloride, and

[0064] ditallowdimethylammonium chloride.

[0065] Materials that can be used to opacify compositions of theinvention include fatty esters, opacifying polymers, such as styrenepolymers, like OPACIFIER 653 from Morton, International, Inc.; and fattyalcohols. The following is a non-limiting list of fatty alcohols.

[0066] cetyl alcohol;

[0067] stearyl alcohol;

[0068] cetearyl alcohol;

[0069] behenyl alcohol; and

[0070] arachidyl alcohol.

[0071] Conditioning compositions of the invention which are not clearalso can include Lexamine S-13, dicetylammonium chloride, andceteareth-20.

[0072] Lightening and/or highlighting the hair with the compositions ofthe invention is carried out by conditioning the hair, that is, (1)applying water to said hair (or starting the process with hair that isdamp because it has already been shampooed); (2) applying to said hair alightening and highlighting effective amount of a conditioningcomposition of the invention; (3) rubbing said hair with the hands or ahair appliance such as a comb; and (4) rinsing said hair with water.Each application of a composition of the invention results in a smalldegree of lightening and/or highlighting of the hair. By using acomposition of the invention on a daily basis, the hair can be graduallylightened and highlighted until it reaches the desired state. At thatpoint, conditioning with a composition of the invention is ceased, andhair of the desired color has been obtained until it grows out.

[0073] A person who used the conditioner compositions of the inventionand also spends time in the sunlight may achieve hair lightening and/orhair highlighting more quickly than someone who uses the compositions ofthe invention but does not spend time in the sunlight. This is due tothe additive effects of the bleaching of hair by sunlight and thechemical action of the conditioning compositions of the invention.

[0074] It will also be appreciated that the compositions of theinvention have the advantage of enabling the user to obtain just thedegree of highlighting and/or lightening that he or she desires at whichpoint conditioning of the hair with the compositions of the invention isstopped, and this desired hair coloring will remain until the hair growsout.

[0075] Usually, some lightening or highlighting of the hair will benoticeable within the first ten to fourteen consecutive days ofconditioning with a composition of the invention. Often, a compositionof the invention will be used for up to about thirty consecutive days.However, as mentioned above, an advantage of the invention, is that acomposition of the invention may employed for more or less consecutivedays than listed above, as desired by the user. In addition, theconditioning compositions may be employed every other day, or at evengreater intervals as desired. If compositions of the invention are notemployed on consecutive days, use may be made of the consumer'scustomary non-bleaching conditioner on the days when the bleachingconditioner of the invention is not being used. Moreover, after beingapplied, the conditioner may be left in the hair for a few seconds, orthirty seconds, or as long as 15 minutes. The longer the conditioner isleft in the hair, the more the hair will be hilighted or lightened for agiven application.

[0076] It will also be appreciated that the conditioning compositions ofthe invention also have the benefit of conditioning the hair at the sametime as lightening or highlighting the hair. The conditioningcompositions of the invention also have acceptable sensory qualities.

[0077] Compositions of the invention were used as conditioners and wereevaluated by a trained panel of observers and found to lighten andhighlight hair.
